In yet another exemplary embodiment, the terminal device may be a millet mobile phone, and the terminal device is provided with two cameras, one of which is a wide-angle camera and the other of which is a telephoto camera. The original image is a video frame in the video. When the terminal equipment records the video, in the recording process, the wide-angle camera and the long-focus camera are simultaneously called to normally record the video, the aperture values of the wide-angle camera and the long-focus camera are both 4, the zooming capability of the long-focus camera is called immediately, and the focus segment is quickly drawn to record the video. In the process of recording a video in a zoom-in section, the aperture value of the telephoto camera changes. For example, the aperture value of one of the video frames may be 8. In the present exemplary embodiment, the acquiring, by the terminal device, the photographing information of the photographed photo may include: information on the number of cameras, information on the type of camera, information on the apparatus of the photographing apparatus, and an aperture value.

In the embodiment of the present disclosure, in the target image, the original image and the target watermark may be located in different image layers, and the image layer where the target watermark is located may be located above the image layer where the original image is located.

In one embodiment, before step S301, the method may further include: when a photographing instruction is received, at least two original images are photographed based on different photographing information. And after step S303, may further include: storing at least two target images carrying target watermarks; the target watermarks carried by the at least two target images are different. For example, in the continuous shooting mode, after the terminal device receives a shooting instruction, if shooting information changes during shooting, the terminal device may shoot at least two original images based on different shooting information. Then, the terminal device may obtain corresponding target watermarks according to respective shooting information of the at least two original images, so as to obtain at least two target watermarks. Then, the terminal device may add the at least two target watermarks to the corresponding original images to obtain at least two target images carrying the target watermarks. Because the shooting information of at least two original images is different, the target watermarks carried by at least two target images are different. Therefore, the shooting information of the current image can be conveniently identified by the user through the watermark, and the use value of the watermark can be improved. It should be noted that the image processing method in the continuous shooting mode is similar to the image processing method in the video recording process, and will not be illustrated here.

In the embodiment of the disclosure, the target watermark carried by the target image includes at least one of shooting parameters, scene mode information and camera working state information, so that the target image can show the original image in the target image under what shooting condition, and the use value of the watermark and the circulation and the dissemination of the image are improved. In addition, in the process of image circulation, the hardware capability of the mobile phone can be better exposed and highlighted.

In the embodiment of the present disclosure, since the shooting information of the shot original image can be acquired, and the target watermark is obtained according to the shooting information and the corresponding relationship between the shooting information and the watermark, the target watermark carries the shooting information of the original image. And because the shooting information comprises at least one of shooting parameters, scene mode information and camera working state information, the target watermark carries at least one of the shooting parameters, the scene mode information and the camera working state information. In this way, the target watermark is added to the original image, and the obtained target image carrying the target watermark carries at least one of shooting parameters, scene mode information and camera working state information. Therefore, according to the technical scheme of the embodiment of the disclosure, different watermarks can be correspondingly generated according to different shooting information, so that a user can identify the shooting information of the current image through the watermarks, and therefore, the use value of the watermarks can be improved, and the improvement of the circulation and the propagation of the image carrying the watermarks is facilitated.

Fig. 8 is a flowchart illustrating an image processing method according to another exemplary embodiment. In this embodiment, the original image may include a foreground image and a background image. And the layer where the background image is located is positioned below the layer where the foreground image is located. For example, when the terminal device shoots a person image in the portrait blurring mode, the shot original image includes a foreground image and a background image, the foreground image is a clear person image, the background image is a blurred background image, and a layer where the background image is located below a layer where the foreground image is located. On the basis of the embodiment shown in fig. 1, after the step S301, the following steps S801 to S803 may be further included:

in step S801, a background image in the target image is blurred, and a blurred background image is obtained.

In one embodiment, the terminal device may provide a function of adjusting the degree of blurring of the background image in the target image. After the terminal device obtains the target image carrying the target watermark, the terminal device may perform blurring processing on the background image in the target image according to the received control instruction for adjusting the blurring strength of the background image, so as to obtain a blurred background image.

In step S802, the blurring strength of the blurred background image is determined.

In one exemplary embodiment, the image may be divided into 100 blur levels from sharp to gaussian blur, each blur level corresponding to a blurring intensity value. For example, when an image is sharp, the blurring level is 1, the blurring level 1 corresponds to a blurring intensity value of 1, when the image is gaussian blurred, the blurring level is 100, and the blurring intensity value of 100 corresponds to the blurring level 100. The terminal device may store a correspondence between the blur level and the blurring strength.

In the above exemplary embodiment, the terminal device may determine the blurring level of the background image after blurring, and then obtain the blurring strength of the background image according to the blurring level of the background image and the corresponding relationship between the blurring level and the blurring strength.

In step S803, the target watermark is updated according to the blurring strength.

In one embodiment, the blurring strength of the background image is different, and the corresponding target watermark is different. Therefore, when the blurring strength of the background image is updated, the above-described target watermark is also updated.

In one embodiment, the shooting information includes shooting parameters including aperture values, the target watermark carries an aperture value for shooting the background image, as shown in FIG. 9, the target watermark 91 may be carried ON the target image, wherein the aperture icon 911 in the target watermark 91 indicates that the aperture value for shooting the background image is 4, the words SHOT ON MI PHONI DUA L CAMERA912 "MI PHONE" indicates a cell PHONE, and "DUA L CAMERA" indicates that the terminal device has two CAMERAs, as shown in FIG. 10, step S803 may include the following steps S1001-S1003:

in step S1001, a target aperture value is obtained according to the blurring strength and the correspondence between the blurring strength and the aperture value.

In one embodiment, the correspondence between the blurring strength and the aperture value is stored in the terminal device in advance. For example, the aperture values 2 to 22 are divided into 100 levels, each level corresponding to one blurred intensity value. For example, the blurring strength value corresponding to aperture value 2 is 1, the blurring strength value corresponding to aperture value 2.2 is 2, the blurring strength value corresponding to aperture value 2.4 is 3, … …, the blurring strength value corresponding to aperture value 21.8 is 99, and the blurring strength value corresponding to aperture value 22 is 100. The terminal device may obtain the target aperture value according to the determined blurring strength of the background image and the corresponding relationship between the blurring strength and the aperture value.

In step S1002, a new target watermark is obtained according to the target aperture value and the corresponding relationship between the aperture value and the watermark.

In one embodiment, the terminal device stores the corresponding relationship between the aperture value and the watermark in advance. The terminal equipment can obtain a new target watermark according to the target aperture value and the corresponding relation between the aperture value and the watermark. For example, when the target aperture value of the blurred background image obtained after the blurring process is 8, a new target watermark 92 as shown in fig. 11 may be obtained according to the correspondence between the aperture value and the watermark. Here, aperture icon 921 in target watermark 92 indicates that the aperture value of the captured background image is 8.

In step S1003, the target watermark is updated to the new target watermark.

In one embodiment, after obtaining the new target watermark, the terminal device may update the target watermark before the blurring process to the new target watermark.

In the embodiment, when the blurring degree of the photo is edited in the middle and later period of the photo album, the user can see that the aperture of the watermark is changed along with the change of the blurring strength value, which is a feedback of the visible capability of the photographing software.

In this embodiment, in the process of adjusting the blurring strength of the background image in the target image, the target watermark may be updated according to the blurring strength of the background image, so as to provide a feedback mode of the visible capability of the photographing software.
